This library provides Rust-friendly interfaces to the CMSIS DSP library, which implements many mathematical and signal processing operations for ARM Cortex-M processors.
Complete documentation for the underlying library can be found here.
Different versions of the library will be linked depending on the type of processor the code will run on. You may need to enable some Cargo features depending on the target:
- Cortex-M7: Enable the feature
cortex-m7. Also, if the processor has a double-precision floating point unit, enable the
- Cortex-M33 (target
thumbv8m.main-none-eabihf): If the processor supports DSP instructions, enable the
All other targets will be configured automatically based on the target passed to cargo. If you forget to enable a feature, everything should still work but it may be slower.
